  Objective-C

  typedef NSString *FIRStorageHandle

• FIRStorageVoidDataError

  Block typedef typically used when downloading data.

  Declaration

  Objective-C

  typedef void (^FIRStorageVoidDataError)(NSData *_Nullable, NSError *_Nullable)

  Parameters

  data	The data returned by the download, or nil if no data available or download failed.
  error	The error describing failure, if one occurred.

• FIRStorageVoidError

  Block typedef typically used when performing binary async operations such as delete, where the operation either succeeds without an error or fails with an error.

  Declaration

  Objective-C

  typedef void (^FIRStorageVoidError)(NSError *_Nullable)

  Parameters

  error

  The error describing failure, if one occurred.

• FIRStorageVoidMetadata

  Block typedef typically used when retrieving metadata.

  Declaration

  Objective-C

  typedef void (^FIRStorageVoidMetadata)(FIRStorageMetadata *_Nullable)

  Parameters

  metadata

  The metadata returned by the operation, if metadata exists.

• FIRStorageVoidMetadataError

  Block typedef typically used when retrieving metadata with the possibility of an error.

  Declaration

  Objective-C

  typedef void (^FIRStorageVoidMetadataError)(FIRStorageMetadata *_Nullable,
                                              NSError *_Nullable)

  Parameters

  metadata	The metadata returned by the operation, if metadata exists.
  error	The error describing failure, if one occurred.

• FIRStorageVoidSnapshot

  Block typedef typically used to asynchronously return a storage task snapshot.

  Declaration

  Objective-C

  typedef void (^FIRStorageVoidSnapshot)(FIRStorageTaskSnapshot *_Nonnull)

  Parameters

  snapshot

  The returned task snapshot.

• FIRStorageVoidURLError
